the class SpelExpression method parseExpression.

private Expression parseExpression() {
    // Support template parsing with #{ } delimiters
    ParserContext parserContext = new TemplateParserContext();
    Expression expression = expressionParser.parseExpression(expressionString, parserContext);
    return expression;
}

Example 2 with TemplateParserContext

the class SyslogEventForwarder method getTranslatedMessage.

/**
     * Gets the translated message.
     *
     * @param event the event
     * @param node the node
     * @param msgFormat the message format
     * @return the translated message
     */

    StandardEvaluationContext context = new StandardEvaluationContext(event);
    if (node != null) {
        context.setVariable("node", node);
    }
    ExpressionParser parser = new SpelExpressionParser();
    Expression exp = parser.parseExpression(msgFormat, new TemplateParserContext("${", "}"));
    try {
        final String msg = (String) exp.getValue(context, String.class);
